The present invention relates to a hot air deflector for hot air heatingisystems which usually have connection with a room through ,7 an opening in the floor or wall thereof and i has for some of its objects to provide, in a manner as hereinafter set forth, a deflector of this character which will be simple in construction, strong, durable, eiiicient and reliable in use, attractive in appearance, and which may be manufactured and installed at low cost. j

-Another important object of the invention is to provide a hot air deflector through the medium of which the air in a room will be caused to circulate in such aimanner to materially reduce the accumulatingof dirt, dust,*lint, etc. on the walls and ceilingcof said room. 7 Another very important object of the invention is to provide a hot air deflector of I the character .described embodying a novel construction, combination and arrangement of parts through the medium of which the air of the room in which the deflector is illstalled will be moistened.

Allot the'foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding'parts throughout the several views, and

Referring now to the drawings in detail, .5 it will be seen that the embodiment of the invention which has been illustrated com prises a. cabinet designated generally by the reference numeral 1, said cabinet being of... any suitable material, preferably metal, and 3 including integral front and side walls 2 and 3, respectively, a back or rear wall 4 secured, as at 5, to thejside wa'1ls'3, and aremovable top which isdesignated generally by thereference numeral 6. The vertical. "corner portions of the cabinet are torniedto enhance the appearance of said cabinet, as at 7 Of course, the cabinet may be otherwise ornamented in any suitable manner.

The top 6 includes the spaced'upper and lower sheets 8 and.9, respectively, having the. abutting downturned skirt portions 10 and 11, respectively, theportion 10 termig nating in an internal, upturned flange12 en p gaged with and retaining theportion 119 Thus,-a depending flange is providedjwhich encircles the upper portion of the walls of the cabinet which provides an attractive 'fit for the top. Between the sheets 8. and 9 of the top there is disposed a filler '13, preferably .3 of heat insulating material. The lower portions of the wallsof the cabinet 1 are spaced above the-floor 14 to provide the air inlet openings 15 at'the lower end'of the cabinet. Thus, the corner portions 7 project below the cabinet 'walls and constitute supporting legs for the cabinet The front wall 2 of the cabinet is provided, in its upper portion, with an outlet opening 16. The

marginal portions-ofthe material of the r front wall 2 around the opening 16 are folded inwardly upon saidwfront wall to provide the flanges 17 which, in turn, are cutandbent to provide the oppositely disposed flanges or retainers 18 in which a perforated plate 19 is mounted. i A vertical inlet pipe is designated byth'e.

reference numeral 20, said pipe being preferably rectangular.- in horizontal section and.

beingengageable in the usual opening 212 we a provided, in the floor 14. The pipe 20, of course, rises from the floor 14 in the cabinet 1.

The lower portion of the pipe 20 is formed to provide an external supporting flange 22 engageable with the floor 14 and the upper portion of said pipe 20 is formed to provide the con'iparatively small external flange 23 upon which rests the enlarged lower portion 24 of a vertical conduit which is designated generally by the reference numeral 25. The rear wall 4 of the cabinet 1 also constitutes the rear rail of the conduit 25. p The conduit 25 is closed at its upper end, as at 26, the end 26 having an upturned flange 27 abutting the rear wall 4 of the cabinet. In the upper portion of its front, the conduit 25 is provided with an outlet passage 28 around which the material of said conduitis bent inwardly upon itself, as at 29.

A damper 30 rotatably mounted in the pipe 20 on the pintles 31 secured thereto and journaled in said pipe, one of said pintles being angular to provide an adjusting handle 32. As best seen in Figure 4 of the drawings.

small coil spring 33 encircles theother pintle 31' and is engaged with the damper 30 for 'yieldinglv urging said damper against one wall of the pipe Y20 and in, this manner the damper is frictionally retained in adjusted position. The damper SOis operable by in serting a hand through theside opening: 15 in the lower portion of the cabinet 1 which is adjacent the handle 32.

Mounted horizontally on an intermediate portion of the conduit 25 at a point spaced below the passage 28 is a shelf 34 having a front 35 and sides 36, said sides 36 projecting 're'arwardly adyacent the sides of the conduit 25 and being rigidlvsecure'd thereto by any suitable means, as at '37. Thus, the shelf 34 is securely mounted in position on the conduit 25. The shelf 34 is spaced from the front and sidewalls of the cabinet 1 to provide air passages therebetween. Further, the conduit is also spaced from the front and sidewalls of the cabinet forthe vertical passage of air. Flanges 88 are provided on the upperportions of the side walls 36 and are formed to define channels for the reception of the end portions of a substantially U-shaped hood 39, said hood 39 being readily removable when the top 6 of the cabinet is removed. The hood 39, when in positlon s engaged against the upperportion of the eonduit25, as illustrated to advantage in Figure 2 of the drawings. An

.external flange 40 is provided on the rear portion of the hood 39. The reference numeral 41 designates a handle on the top of the hood 39. The hood 89 is positioned to the rear of the perforated plate 19 and is spaced therefrom. The shelf 34 is adapted to hold water pan 42 to which access may be conveniently had for filling by simply removing "the top 6 and the hood 39.

In case the'hot air opening from the heating plant to the room is through a wallinstead of a floor, the pipe 20 is positioned as indicated in broken lines in Figure 2 of the drawings, the rear wall 4 of the cabinet 1 being provided'with an opening for the reception of one end portion of said pipe 20. This is permitted by reason of the fact that the conduit 25 is mounted on the rear wall of the cabinet and secured, as at 43. Of course, when the device is thusinstalled, the lower end of the conduit 25 may be closed.

As will be obvious, the heated air passes upwardly in the conduit 25 and is directed forwardly through the passage '28, through the hood 39 immediately above the water pan 42 and then passes through the perforated plate 19 into the room. Cold air is drawn into the cabinet from the room through the openings 15 and passes upwardly around the conduit 25 and is returned to the room through the perforated plate 19 andthe opening 16. The upper portions of the walls of the cabinet 1 are turned inwardly to provide the horizontal supporting flanges 44 on which the top 6 rests. At their lower ends, the supporting legs of the cabinet are turnedinwardiv, at 45 (See Figures 3 and 4 of the drawlugs). I W It is believed that the many advantages of a hot air deflector constructed in accordance with the present inventionwill be readily understood, and although the preferred embodiment of theinvention is as illustrated and P, described, it is to beunderstood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will'fall within the scope of the invention as claimed.
